samba - Jul 2004 - net rpc vampire fails to set passwords for machine accounts

Hi all,

I'm really lost here, I do net rpc vampire and it works perfectly for 
user accounts (sets NTLM pass etc) and creates machine accounts, but 
fails to allocate their password hashes, I think it's calling the 
smbldap-useradd utility to add accounts for machines, but I don't see 
why this would make the hashes transfer for users but not machines?

Any help much appreciated.

Regards
Eric Bennett
